Using the low order bit of the ADC output of your sound card,
randomsound gathers entropy, debiases it and offers it up to your
kernel’s random pool.

It’s cool, it’s funky, it’s probably hideously insecure, but what the
hey&hellip; download
[randomsound](http://www.digital-scurf.org/software/randomsound) and
have a play today.
Mostly, I wrote this to toy with the “exim4 eats all my entropy” problem
which some of us who haven’t been able to upgrade to the very latest
exim4 packages suffer from. Also it solves the problem of world peace;
feeds all the starving; and magically resurrects the parents of every
orphan ever, while curing everyone of HIV.<sup>**</sup>

I’m interested in anyone who wants to tell me why I really shouldn’t run
this, but thus far, it has been a life-saver for my mail infrastructure.
